The headbox is a device for pulp to be put on the net on the paper machine. It is connected with the pulp flow system in front of the paper machine, and through the pulp distribution device, rectifier (such as slurry roller), weir plate nozzle, weir pool and other components, it is uniformly and stably flowed along the entire width of the paper machine, creating good preliminary conditions for the formation of paper sheets in the paper machine net.
1. Effectively disperse fibers. High turbulence headbox can generate high-intensity micro-turbulence, which can effectively disperse fibers, prevent fiber precipitation and re-flocculation, and effectively improve the strength of paper sheets.
2. Evenly distribute paper materials along the transverse direction of the paper machine. (Determines the transverse quantitative distribution of the paper web)
3. Stable spraying ensures that the pulp speed and the wire speed are coordinated. (Determines the longitudinal quantitative distribution of the paper web)
